Pagina 619 - This acid precipitates the coloring matter which is held in solution, and prevents the undissolved madder from fermenting, or otherwise decomposing. When the water has drained from the madder through the filter, the residuum is taken from off the filter, and put into bags. The bags are then placed in a hydraulic press, to have as much water as possible expressed from their contents.
Pagina 619 - I place a quantity of stones, or gravel, and over the stones, or gravel, common wrappering, such as is used for sacks. Below the bricks is a drain to take off the water which passes through the filter. In a tub adjoining the filter is kept a quantity of dilute sulphuric acid, of about the specific gravity of 105, water being 100.
Pagina 795 - It occurred to me, therefore, that if the surface of the plate was engraved, an impression might be obtained. This was found to be the case ; for on detaching the precipitated metal, the most delicate and superficial markings, from the fine particles of powder used in polishing, to the deeper touches of a needle or graver, exhibited their correspondent impressions in relief with great fidelity. It is, therefore, evident that this principle will admit of improvement, and that casts and moulds may...

Pagina 612 - Alizarin has the following properties : — When heated on platinum foil it melts and burns with a bright flame. When heated in a glass tube closed at one end it melts and gives yellow fumes, which condense on the colder parts of the glass, forming an oil, which soon congeals to a mass of orange-coloured crystals possessing a considerable lustre, which are unchanged alizarin. A carbonaceous residue is usually left in this case, but I have no doubt that by carefully heating it might be entirely volatilized.

Pagina 596 - A manufacturer of carmine, who was aware of the superiority of the French colour, went to Lyons for the purpose of improving his process, and bargained with the most celebrated manufacturer in that capital for the acquisition of his secret, for which he was to pay a thousand pounds.
Pagina 808 - ... are less ; in other instances, where the process was regular and the metal homogeneous, the fracture extended quite through the metal to upwards of one-eighth of an inch in depth. I have observed this phenomenon in about nine instances, in several of which the explosion took place even in the liquid, by striking the deposit against the glass containing vessel ; and in one instance it occurred after the metal had been well washed with dilute hydrochloric acid, dried, and had remained out of the...
